.To all whom, it may concern,.-

Be it known that I, NAPOLEON JOSEPH COTE, ofthe city of Montreal, in theDistrict of Montreal and Province of Quebec, Dominion of Canada, haveinvented certain new and useful Improvements in Apparatus for FormingHeel Counters or Stifeners; and I do hereby declare that the followingis a full, clear, and exact description of the same.

rPhe present invention relates to improve-l ments in heel-countermachines, and, in part, more especially to that class where shapedrollers are used in place of block-dies as the matrices.

The improvements have for their object economy in construction and toattain efficiency with certainty and rapidity in opera-` tion. I propelthe punches bythe revolution of a screwed shaft working in threadedbearings and having cross-heads, to which the punches or formers areattached; butthe invention embodies certain other novel features ofparticular value in the formation of a perfect heelcounter or stiffener,which are hereinafter described and specifically claimed.

For full comprehension ofthe improvements, reference must be had to theaccompanying` drawings, forming part of this specification.

Figure l represents a plan view of my ma chine constructed with foursets of formers. Fig. 2 is a side elevation of part of same. F10'. 8 isa transverse sectional elevation (enlarged) taken on line w, Fig. 1.Fig. t is a sectional plan of Fig. 8. Figs. 5, G, and`7 are respectvelydetail plan, section, and elevation of one ofthe forming-'rollers Fig,Sis a detail view of puncher or former. Fig. 9 is a det-ail view ofrollers for forming upturn.

Similar letters of reference indicate like parts.

Letter A represents the bed or frame of the machine, of oblong or otherdesired shape, and of suitable strength. On its upper side are two ormore bearings, a c, for a screwshaft, B, uponwhich is mounted a pulley,b, around which a belt is passed for rotating said shaft. This shaft isrepresented in the drawings as threaded only at one end, as I have foundthat this answers the purpose; but and mount extra pulleys upon it, aswill be readily understood, and thread the bearings c a accordingly. Tothis shaft, at both ends, are attached cross-heads B B2, to which arebolted the punches or forniers O O O/ Or Of these, four are shown; butof course two or more maybe used, as desired, according to the number ofcounters or stiffeners to be made at each stroke. These cross-heads andpunches slide in grooves or ways af a', formed on the wood frame A, andthe punches are so attached to the crossheads that their front ends maybe elevated or depressed in order to provide for different thicknessesof leather in the npturn of the counter. rlhis is accomplished byadjusting a set-screw, c, working through a strap, c, bolted to theframe and crossing the punches, as seen in Figs. I and S, and alsoadjusting a set-screw, ci, working in an elongated slot, 0*, in the rearend of the punch.

D D D represent rollers of the shape shown in detail in Figs. 3, 6,`and7. The spindlesof these are securely but loosely lctinto threesidedframes Or boxes d. (Shown more fully in Figs. 3 and a.) As seen in Figs.3, Li, 5, 6, and 7, each of lthe rollers Dhas a projection, d?, formedon it, concave on its front side, so that when the punch or formercarries the blank forward the projections di of two rollers are closetogether and present a curved recess of the same contour as the frontend of the punch, into which the blank is forced, and its front endpressed into the proper shape before the rollers D commence to rotate,suitable springs, d di, (fastened at one end to any convenient part ofthe fra1ne,) pressing on a iiattened surface, dt, on each -roller andgiving the required resistance while the front of the counter is beingformed as above. The frames or boxes d are let into grooves d in the bedA, so as to move therein, as shown in Fig. 3. To keep the frames d inproper position, a plate, E, is placed over same and supported at theends by the standards E E', which in turn are securely fastened to orcast in one with the bed-plate A. The lower surfaces of the plates E arerecessed, as well as the bedplate A, (shown more particularly in Fig. 3at Z. Immediately in front of each pair of boxes IOO Y through the sidesof the boxesV el d, and sliding in the same manner, but independently,are two fiat gates, E2 F2, with an opening or orifice, e, at theirjoints to admit the punch. These gates are for the purpose of guidingthe blank straight toward the forming-rollers D D, and the orifice c insame will offer the first resistance to the punch carrying the blank,and bends the latter in such a manner that it cannot slip to one side orthe other before or while it is acted upon by the rollers D. These gateshave pressure-springs c e' at either side to give the necessaryresistance as the punch passes between them, and to throw said gatesback into place when the punch recedes.

To give pressure to the rollers D D when the punch C forces itswaybetween each pair, the ends ot' strong steel springs F F presskagainst the outside of the boxes (l, and these springs are securelyfastened near their outer extremities to the standards ff, and these inturn are secured to the bed-plate A, or may form part of the same. Thestandards f are furnished with screwed projections and nuts, so that thepressure of the springs may be regulated.

Between each set of springs, and immediately behind each pair of rollersD, an opening, G, is made in the bed, through which the finishedcounters can fall.

To form the upturn ofthe heel counter or I stiffener, two rollers, G andH. are carried in the lower part of the boxes or frames d in such mannerthat part of these rollers will project slightly above the inner face ofthe box. These upturn-rollers are of the construction shown in detail inFig. Q-viz., that marked G (being the first which the counter-blankstrikes as it passes between the rollers D) has a deep thread, g", cutupon its central part, which will crease or indentthat part ofthe blankwhich is turned up, and thus allow it to assume the proper curve, whilethe roller marked H is plain on its surface and serves to atten the partso creased and curved, and thus complete the upturn. Both of theserollers have long` spindles g It', which project d and abut l againstthe standards of the bed'plate, so as to prevent any end mot-ion, andkeep the operating-surfaces of the upturirrollers always in their properplace, Fig. 4. The boxes d d slide freely without disturbing theserollers.

The operation of my machine will be clearly understood from theforegoing and from the drawings; but I may say that when a belt (drivenfrom a counter-shaft) is placed over the pulley b the revolution ofthescrewed shaft will force one set of punches O between the rollers atthat end of the machine, thus forming a counter with each punch.

By means of a twisted belt and fast and loose pulleys on thecounter-shaft, or by any other convenient mechanism, the shaft B will berotated in the opposite direction, and draw back the first set ofpunches, and force those, C, at the other end forward between theirrollers and form another lot of counters, and so on.

The blanks are fed in frontof the gates E2 F'l by hand or any suitableautomatic device.

Reference is hereby made to my application for patent on heel -stiftenermachine, filed March 16. 1883, No. 88,404, and Ido not here in claim thematter shown in that application.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is as follows:

l. In a machine for forming heel counters and sti tfeners,thecombination,with the bed A, of the revolving screw-threadeddriving-shaft B, having a belt-pulley, Z1, the cross-heads B B2,connected to opposite ends of the shaft, and punches or formersconnected to the crossheads, substantially as described.

2. In a machine for forming heel counters and stitfeners, thecombination, with a pairot' rollers, D D, and their boxes d d andsprings F, of the gates E Ef, having central orifice, e, and springs e,arranged and operating substantially in the manner and for the purposedescribed. i

3. In a machine for forming heel counters and stiffeners, the rollers DD, having projections (Z2, curved on their face, so as to form front ofcounters, in combination with springs for opposing the rotation of saidrollers, and a punch or former, substantially as specified.

4.. In a machine for forming heel counters and stiffeners, thecombination, with a punch or lower roller, D D, and sliding boxes d d,of the threaded roller G and plain roller H, for forming the upturn,substantially as specified.
